Abstract

Entrapment of the ulnar nerve around the elbow is the second most common compression neuropathy in the upper extremity. Many anatomical regions that possibly compress the ulnar nerve around the elbow joint have been described, however few cases below the flexor carpi ulnaris muscle have been reported. A case with ulnar nerve entrapment at the flexor pronator aponeurosis, secondary to surgery is reported in this study.

Keywords: cubital tunnel syndrome, flexor pronator aponeurosis, ulnar nerve

Figures and Tables

Figure 1

(A) Radial head fracture and coronoid process fracture of the right elbow were shown on plain radiograph. (B) Radial head and coronoid process were fixed with plate and screws.

Figure 2

(A) Medial epicondyle (black arrowhead) and humeral head of flexor carpi ulnaris (white arrowhead) are shown. Note that the fascia of flexor carpi ulnaris is already divided. (B) The ulnar nerve is compressed by the deep flexor pronator aponeurosis (black arrow).
